ROHM Power-Management-Related
Power management-related components are electronic components that manage power supply, such as the power supply required for electronic circuits, prevention of power supply backflow, and improvement of power efficiency. Mounting types include through-hole mounting, surface mounted IC package and surface mounted module. Power supply ICs include AC / DC converters, voltage regulators and PoE controllers. A PoE controller is an IC that can supply power alongside data communication over Ethernet. It is suitable for environments where power cable installation is difficult. To prevent power supply backflow, a low-loss OR connection module that uses a MOS-FET switch mechanism is suitable instead of a conventional Schottky diode. Power factor correction ICs are components that correct the phase difference between voltage and current to improve power efficiency.
